This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and correspondingly not compensated for and can thin the engine out and can then permit the engine to rev taking place taking into account not desired causing rasping running. As its a mechanical malfunction it tends not to outlook on the defect open and you can sometimes listen a hissing noise bearing in mind the engine running.
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. next I unplug it and govern the motor, the car runs scratchy and at 850ish. I can and no-one else guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much control in the oscillate of rpm though? I think it on your own adjusts it nearly 1k..
